Abstract
Abstract Electric power transmission to an undersea installation (4) is effected by movement of a conductor assembly (20) through a guide pipe (11) under fluid pressure acting on a piston (25) at the leading end of the assembly. The fluid can be a dielectric oil and the assembly (20) can be hollow for circulation of the oil for cleaning contacts and for cooling purposes as well as for operating equipment in the undersea installation and for monitoring its performance.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
58 words
1 . A system for electrically connecting together first and second stations, the system comprising a guide pipe extending between the two stations, and electrical conductor mears arranged to be moved along the guide pipe, at least in part under fluid pressure, from the first station to effect electrical connection with co-operating conductor means at the second station.
Claim 2
Dependent Claim
58 words
1 . A system for electrically connecting together first and second stations, the system comprising a guide pipe extending between the two stations, and electrical conductor mears arranged to be moved along the guide pipe, at least in part under fluid pressure, from the first station to effect electrical connection with co-operating conductor means at the second station.
Claim 3
Dependent Claim
28 words
A system as claimed in claim 1 having supply and return paths for the pressure fluid to permit limited or complete return movement of the movable conductor means.
Claim 4
Dependent Claim
35 words
A system as claimed in claim 2 wherein the movable conductor means is hollow, the fluid supply and return paths being respectively within the conductor means and between the conductor means and the guide pipe.
Claim 5
Dependent Claim
28 words
A system as claimed in claim 3 wherein the hollow conductor means comprises a plurality of concentric conductor pipes separated by one or more sleeves of dielectric material.
Claim 6
Dependent Claim
48 words
A system as claimed in claim 2, 3 or 4 wherein the conductor means comprises electrical conductors and a protection pipe within and/or around the conductors, the or each protection pipe co-operating with the guide pipe and/or the electrical conductors to define one or more additional fluid paths.
Claim 7
Dependent Claim
44 words
A system as claimed in claim 5 wherein the other station is an undersea gas/oil extraction station and wherein at least one of the additional fluid paths is employed for conveyance of extracted gas/oil to the one station after establishment of the electrical connection.
Claim 8
Independent Claim
53 words
A system as claimed in any preceding claim wherein the second station is an undersea station comprising a base frame receiving a retrievable unit carrying the co-operating conductor means, the guide pipe being secured to the base frame to permit movement of the movable conductor means part to engage the co-operating conductor means.
Claim 9
Independent Claim
50 words
A system as claimed in any preceding claim having spaced along the movable conductor means a plurality of piston elements operative between the conductor means and the guide pipe, the or each piston element being spaced from the conductor means leading end and having valve means providing appropriate pressure drops.
Claim 10
Independent Claim
43 words
A system as claimed in any preceding claim wherein the co-operating conductor means and the leading end of the movable conductor means are so arranged that the pressure fluid flushes contact areas of the conductor means prior to establishment of the electrical connection.
Claim 11
Independent Claim
41 words
A system as claimed in any preceding claim wherein the co-operating conductor means and the leading end of the movable conductor means are arranged for reception of an annular winding within an outer annular winding to establish the electrical connection inductively.
Claim 12
Dependent Claim
81 words
11: A system as claimed in any preceding claim wherein circulation of pressure fluid after establishment of the electrical connection effects at least one of: (a) continuous flushing of contact areas of the conductor means; (b) cooling of the conductor means; (c) driving of equipment within the second station; (d) monitoring condition and/or performance of equipment at the second station; (e) circulation of pressure fluid within the second station; and (f) protection against entry into ths system of ambient fluid material.
Claim 13
Independent Claim
62 words
A method of electrically connecting together first and second stations having a guide pipe extending therebetween, the method comprising the step of advancing an elongate conductor means along the guide pipe from the first staticn to establish electrical connection with co-operating conductor means at the second station, at least part of the advance of the conductor means being effected under fluid pressure.
Claim 14
Independent Claim
62 words
A method of electrically connecting together first and second stations having a guide pipe extending therebetween, the method comprising the step of advancing an elongate conductor means along the guide pipe from the first staticn to establish electrical connection with co-operating conductor means at the second station, at least part of the advance of the conductor means being effected under fluid pressure.
Claim 15
Dependent Claim
87 words
A method as claimed in claim 12 wherein the pressure fluid is circulated in the guide pipe after establishment of the electrical connection, so as to effect at least one of: (a) continuous flushing of contact areas of the conductor means; (b) cooling of the conductor means; (c) driving of equipment within the second station; (d) monitoring condition and/or performance of equipment at the second station; (e) circulation of pressure fluid within the second station; and (f) protection against entry into the system of ambient fluid material.
